Product Description:

The Bosch Rexroth Indramat ADF164B-B05TC0-AS06-A2N2 belongs to the ADF Main Spindle Motors series. It is a liquid-cooled asynchronous motor intended for main spindle duties in CNC machining centers, printing lines, and other automated production cells. Designed as part of a modular drive chain, the unit accepts inverter power, converts it into continuous rotary motion, and supports the precise speed regulation required in high-duty cycles. Its construction uses internal water channels to dissipate heat so the stator remains within thermal limits during prolonged operation.

With a frame rating of 164 and the length code B, the motor offers a compact envelope while delivering the torque density expected from a main spindle drive. The stator is prepared for flange mounting, allowing direct attachment to the machine headstock without intermediate brackets. Incoming power is routed through a junction box positioned on side A, which simplifies cable bends inside the cabinet. A plain shaft couples to chucks or belt pulleys, and the design omits a shaft seal ring to minimize running friction in liquid-cooled service. Only one drive end is supplied, and the opposite side has no second shaft end to conserve axial space.

Dynamic behavior is improved by the S-class balance quality rated at S DIN ISO 2373, which limits residual vibration during high-speed cuts. Feedback is provided through digital servo feedback, enabling the drive controller to read rotor position during each control loop. The copper package uses winding code AS, which corresponds to the resistance and inductance values recognized by ADF-compatible inverters. The connection housing is positioned at the top, keeping coolant lines clear. Standard rolling bearings carry radial and axial forces, and the motor is supplied without a holding brake for spindle applications that rely on external clamping during shutdown.
